add highpass to basic tutorial

[dominikwelke]

hi GEDAI team

thanks for a great new tool to play around with!

I noticed in the python version you don't currently recommend the HP prior to denoising, as you do in the matlab/eeglab tutorial (https://github.com/neurotuning/GEDAI-master/wiki/Tutorials + baked in the GUI).

with all the recordings i tried this step was in fact critical, so here's a small PR if you want to add it.

cheers!
